drm/msm/dpu: Fix uninitialized variable
There is a possibility for an uninitialized *ret* variable to be
returned in some code paths.
Fix this by initializing *ret* to 0.
Addresses-Coverity-ID: 1642546 ("Uninitialized scalar variable")
Fixes: 774bcfb73176 ("drm/msm/dpu: add support for virtual planes")
